VENTILATOR.

Application filed May 15, 1923.` Serial N0. 639,154.v

To all lwhom t may concern.'

Be it known that 1,;EnwAnD T. SPILLMAN, a citizen of the United Statesof America, residing at Columbus, in the county of Franklin andStatefotl Ohio, have invented certain new and useful Improvements inVentilatore, of which the following is a` specification.

My present 'invention relates generally to ventilators and moreparticularly toy roof ventilators, my primary object being the provisionof a ventilator of this type which will work automatically andcontinuously in an effective efficient manner with' free full outlet forthe internal currents and Without back pressure irrespective of thevelocity and direction of the external currents.

A further object is the provision of a ventilator of this type, theconstruction of which insures strength and durability and avoids thenecessity of ,all moving parts and wear, rattling and squeakingordinarily incident theret f A still further object is the provision ofa roof ventilator whose initial cost is low, whose constructionyobviates the necessity for power, andgwhose' upkeep isthereforepractically without expense. f

The preferred embodiment of my invention is shown in theaccomp'anyingdrawing and the further objects as well as the resultf ingadvantages of my invention will be better understood from the. followingdescription by reference to the several ligures of the drawing, whichforms a part ot this speciiication and in which- I Figure 1, Y f

Figurefl is a side elevation of my improvedv ventilator, Y- y Figure 2is a sectional top plan view thereof taken substantially on line 2 2 ofFigure y3 iisfa verticalrsection taken dia metrically therethrough, y

lFigure 4 isV a` horizontal Vsection taken substantially onf line 1f-41of Figure 1,

Figure is a' detail radialsection taken substantially on line 5 5oFigure 2, Figure 6 is a detail perspective view of one'of theshieltlsan'd` Figure 7 is a detail vertical section through the upperportion of the body and the shield holding ring, illustrating one of theattaching brackets for supporting a ring.

Referring now to thesei several figures and particularly to `Figures 1to. 5 inclusive I have shown my improved ventilator made up of avertical cylindrical body 10 at spaced f points around which are'secured the lower portions of a circumferential series of wing plates11, these plates being disposed vertically with their upper portionsprojecting substantially above the upperedge V12 of the4 body 10 so asto form between these upstanding upper portions of the wing plates aseries of outlet lspaces whichy open laterally into the upper portionsof a series ofl circumjacent shields 13.

Above the body 10,'a hood 14, preferably of the shallow conical formshown, is mounted in spaced relation to the upper ends of the wingplates11, .this `hoodgbeing flanged as at l5 and supported by brackets 16which 1 depend therefrom and are secured to the upper portions of thewing plates 11, itbeing noted that thehood not only overliesthe upperend 'of the body 10 ybut outstands therearound and beyond the wingplates 11 J and also the shields 13.

The several wing plates 11 `and shields 13,

it will be noted, are in overlapping relationcircumferentially aroundthebody 10,

the wing plates 11 having along their vertical side edges outstandingflanges 17 wider at their lower ends than at their upper ends andgradually tapering asshown between these ends. The shields 13 on theother hand have along their vertical side -edges inturned llanges 18spaced from one another and from the flanges 17 of the wing plates whichthey overlap, sovasfto form vertical air channels 19 between the sideflanges 18 of each shield' 13V andthe side flanges `17 of adjacent wingv-plates 11 upon opposite sides of said shield and so `as to form largerair channels 20 within eachshield 13 andbctweenvthe side flanges 17 ofadjacent wing plates 11, intothe.latterandlarger channels of which theoutlet-spaces above the'upper edge of the body 10 and betweenthe severalvWing plates .11 directly open. y

By virtue of the tapering of the langes17v and 18 of the wing plates 11and the shields 13 it is obvious that provision vis made tor the passageof air circumferentially between the upper portions of the severalvertical air channels 19 and 2O and by reference to Figure 1 it will benoted that the flanges 18 of the shields 13 are secured at their eX-treme lower ends as by means of rivets and like fastening members 21 tothe lower portions of the wing plates 1l.

The upper ends of the several shields 13 are secured by rivets or likefastening members to a supporting ring 22, this ring being secured inspaced relation around the upper portions of the several wing plates 11by y angular brackets 28 secured at their outer portions to the ring andat their inner portions to the upper ends of the wing plates so that itis thus obvious the entire structure is a rigid assembly of stationarymetal parts whose interconnection and cooperative relation brings aboutthe desired result without necessitating moving parts and therequirenient forrpower in the operation of such parts 4and thusavoidsthe wear, rattling and squeak-'ing ordinarily incident to thepresence of moving parts.,

The relation in connection with the several parts in the rigid assembly'shown and described furthermore brings about a vcircumferential seriesof vertical air channels around the body which, like the body itself,open beneath the hood and which are so formed that provision is madefolrtheir int'er'communication circumferentially around the body so thatirrespective of the direction or the velocity of the outside aircurrents, full free outlet of internal currents is provided for at alltimes without danger of interference as for instance by back pressure, y

My improved ventilatorinvolving as it does a rigid assembly of'partswhich may be stamped from sheet metal, may be prol duced at an initiallow cost and, view of the above it is obvious that in use it will bestrong and durable and practically without i cost of upkeep.

I claim:

1. A ventilator of the type described in-v cluding a verticalcylindrical body, a series of wing platesV disposed vertically aroundand projecting above the body to formi laterally opening outlet spacesbetween their up"- per portions, said wing plates having radiallyoutstanding side flanges, a series o.' shields around and spaced fromthe body opposite the said outlet spaces between the wing plates andoverlapping the saidy wingl plates, having inturned vertical sideflanges spaced from one another and from the wing plate flanges to formvertical air channels around the body between the several flanges.' anda hood spaced above the upper end of the body and the upper'ends'` ofsaid wing plates and shields, below which the upper ends of the saidlair channels open as described. Y

2. A ventilator of the type described including a vertical cylindricalbody, a series of wing plates disposed vertically around and projectingabove the body to form laterally openingoutlet spaces betweentheir upperportions, said wing plates having' radially outstanding side flanges, aseries of shields around and spaced from the body opposite the saidoutlet spaces between the wing plates and overlapping the said wingplates, having inturned vertical side flanges spaced f'romon'e anotherand from'. the wing plate fianges to form Avertical air channels aroundthe body between the several flanges, and a hood spaced above the upperend of the body and the upper ends 'of s'aidn'fing plates and shields,below which the 'upper ends of the said air channels open, the Asaidflanges of the wing plates and tlieshie'lds tapering from relativelywide' lower ends to relatively narrow upper ends asfand for the purposeset forth. l Y Y 3. A ventilator of the type described. iiicluding anupright hollow body, a hdod spaced above said body and outstandingltherearound. and means formling' a series of rer-tival air channelsaroiind the body and opening upwardly beneath the hood, con.- sisting ofa circumjacent series of inner and outer flanged members in( alternatingcircumferentially overlapping relation, the flanges of which are spacedfromon'e another, said inner members being fixed to the said body, and aring supported by the upper ends of said inner members and to which theouter members" are connected.

t. A ventilator of the character described including an upright hollowbody, a' hood spaced above saidY body andoutstanding therearound, aseries of vertical `platesfqs'e'I cured to and extending above theybo'dyl at spaced points' therearound and! having outi standing verticalside flanges,` a second series of plates between andl overlapping theplates of the first series and having inturned ver-A tical side flangesspaced from one another and from the side flanges of the first series ofplates, said second series of plates being f rigidly secured at the'lower ends ofrtlieir flanges to the plates of the first series and tothejbody and having their upper` ends beneath the outstanding portion ofthe hoodg a supporting ring to which the upper ends of the plates of thesecond series 'are connected, and brackets rigidly connecting said ringvat spaced points with' the upper ends f of the plates of the firstseries asdes'cribed.
